After the access device is configured with a device ID, the redirection URL that the access device sends
to a portal client carries the parameter wlanacname and an XML value. The XML value is the configured
device ID. The portal server uses this configured device ID to determine which access device a portal
client is using.

Specifying an autoredirection URL for authenticated

that supports the page auto-redirection function.

Configuring portal detection functions
Configuring online Layer 3 portal user detection
With online portal user detection enabled on an interface, the device periodically sends probe packets
to the portal users on the interface to check whether the portal users are still online, to find portal users
who get offline without logging off.
• If the device receives a reply from a portal user before sending probe packets to the portal user for
the maximum number of times, it considers that the portal user is online and keeps sending probe
packets to the portal user.
• If the device receives no reply from a portal user after sending probe packets to the portal user for
the maximum number of times, it considers that the portal user is offline and stops sending probe
packets to the portal user and deletes the user.
